Synopsis

About Requiem of the Rose King

Richard, the ambitious third son of the House of York, believes he is cursed, damned from birth to eternal darkness. But is it truly fate that sets him on the path to personal destruction? Or his own tormented longings? Based on an early draft of Shakespeare's Richard III, Aya Kanno’s dark fantasy finds the man who could be king standing between worlds, between classes, between good and evil. (Source: VIZ Media)
